Scrub algae and dirt from aquarium rocks with this small footprint, but highly efficient device using the rotary head from a battery-powered toothbrush.

Step 1: Things You Will Need

Picture of Things You Will Need
  • Brush head from a battery-powered toothbrush. I used one for an Oral Action toothbrush. It has a drillable extension on the top that allows for a deeper hole for attachment pin. Other brands may work as well.
  • 3/8 in wood dowel (or larger) -but make sure it will fit in your drill chuck.
  • 1/8 in wood dowel
  • Small saw
  • Drill
  • Pliers
  • Super Glue

Step 2: Separate Rotary Brush From Brush Head

Step 4: Drill Hole in End of 3/8 In. Dowel

Use the same 1/8 in drill bit used for the brush hole to drill a 3/8 in. deep hole in the dowel cut to appropriate length for your aquarium. Don't make dowel any longer than necessary.

Step 5: Super Glue Short Piece of 1/8 Dowel Into Brush Hole

Running at higher speeds is best.

cool idea.. might recommend getting some clear coat enamel paint and putting a few coats on the rod or else it will absorb the water and rot over time. Or you could go with a pvc pipe and cap (or maybe just a sleeve over your dowel rod glued together so water doesn't get into it). just a couple of suggestions to improve the design.

I no longer have a salt water aquarium. But if I did, this would be a godsend. Well done.

I like this concept! I might make one with wider bristles so I can clean the glass of the tank too. Thanks for sharing.
